As water is becoming a rare resource, the onsite reuse and recycling of grey water is practiced in many countries as a sustainable solution to reduce the overall urban water demand. However, the lack of appropriate water quality standards or guidelines has hampered the appropriate grey water reuses. Based on literature review, a non-potable urban grey water treatment and reuse scheme is proposed and the treatment alternatives for grey water reuse are evaluated according to the grey water characteristics, the proposed standards and economical feasibility.

The City

The observed and predicted increase in urban population in the world is creating and will further create severe stress on existing water infrastructures and available water resources. Singapore's population has increased from about 1 million people in the 1950s to almost 5 million currently. The city state has invested massively in a sustainable water supply system, and is regarded by many as a role model for future cities with respect to this topic. Solutions like water reuse, desalination and water demand management have already been implemented. However, city dwellers use much more additional water in the form of virtual water. Their actual water footprint is much higher than only domestic water. Water required for the generation of agricultural and industrial products are imported to cities, and can put a heavy burden on water resources in surrounding and even distant (rural) regions. The city state provides a unique opportunity to analyse virtual water consumption for a city, as required statistical data are available through the national Department of Statistics. For other cities such detailed data are rarely available. Mostly these data are only provided on a national level. This analysis provides a quantification of the actual water use of a future city. The paper describes whether the consumption of agricultural products (in the sense of water for food) is also sustainable in Singapore. The agricultural products that contribute largely to the total water footprint of Singapore – wheat, rice, livestock products and cotton–are analysed and discussed in detail. A sustainable city of the future should account for its impacts beyond its borders. Whether the world can provide for the water and food for an increasing population highly depends on consumption patterns within future cities.

The World

The availability of safe freshwater is diminishing at an alarming rate globally. Increasing human population is stressing water supplies and contributing to water pollution. Population density increases and climate changes including epic droughts in certain parts of the world have led to the utilization of non-conventional water resources. These resources include desalinated sea water and recycled water to meet potable water needs. The water quality in many parts of the world is changing. The burgeoning human population taxes not only water resources but also food supplies, leading to rising demands for irrigation water and consequently to greater potential for water contamination by pesticides, fertilizers, and naturally occurring constituents. The public perception of water is shifting, with growing public awareness of certain groups of contaminants due to media coverage and non-government organization (NGO) concerns. Modern analytical technology has permitted the discovery that minute concentrations of contaminants of distinctly human origin occur in the water cycle. Many of these so-called “contaminants of emerging concern” have been, and will continue to be, detected in potable water supplies. Without question, the propensity for the contamination of fresh water will rise as human population continues to grow. Water treatment technology also continues to evolve. Advanced water treatment processes can provide effective and efficient contaminant removal. This presentation will describe the history, current status, and future implications that the detection of endocrine disruptors and pharmaceuticals will have on water and energy sustainability, with a particular emphasis on water treatment technologies.

Water quality criteria (WQC) is based on the results of scientific experiments and inferences, which prescribe a limit threshold value to pollutants and other harmful factors in water. The system of water quality criteria study is basically a blank circumstance. It’s urgent to establish water quality criteria to adapt with the characters of China water environment to supply theoretic bases for revising water quality standards and managing environment. In this paper, an overview of the water quality criteria, as well as domestic and foreign research progress in theoretical methodology are systematically discussed, furthermore, considering current status of water quality criteria, comprehensive research were pointed out to be done in the future.

Abstract As efforts are made to maintain and improve the water quality in lakes and rivers, the contribution of pollutional loadings from uncontrolled sources becomes more important. A recent study (Whipple, W.J. “BOD Mass Balance and Water Quality Standards”, Water Resources Research, 6 (3), 827, 1970.) of New Jersey rivers presented results that showed that for BOD loadings within selected portions of the rivers the amounts of BOD which could be attributed to controlled sources varied from 7 to 39 percent. With such low percentages subject to control, the economics of improved water quality through advanced waste treatment must be closely examined. In order to do this, it is necessary to have detailed information on the background pollution from uncontrolled sources. This paper is a report of a study to determine such information. Measurements of various parameters to represent the pollutional loadings were made on the storm runoff from a small urban catchment in Ottawa, Ontario. Significant levels of some of these parameters were noted. Variations in concentration were also determined throughout individual storms. This information is useful in determining the expected load from these sources and in attempting to reduce it.

Current Stage

The authors' task was to analyze the development of quality management systems at the current stage in Russia, as well as at the previous stage in the USSR. As a result, we came to the conclusion that the factors stimulating the implementation of ISO 9000 standards are the need to promote products on the world market, as well as the possibility of receiving orders from the state. In the future, strict adherence to these standards will allow enterprises to significantly reduce the likelihood of lawsuits from consumers, which is important in the context of the development of the legislative framework and increased control over the business. The practical significance of the article is the possibility of familiarizing management and personnel with quality services, whose task is to prepare for certification for compliance with ISO 9000 standards in how this process took place in other companies. The originality of this work is to summarize the experience of implementation of ISO 9000 standards at enterprises and to analyze the factors contributing to or hindering this process.
